There are two types of circulating current in parallel inverters: low-frequency and high-frequency circulating current. The low-frequency cir-culating current is parameter related, such as imperfect sym-metry in hardware and dependent control of parallel inverter dead time [18, 19].
The circulating current deteriorates the output current quality and degrades the reliability of the parallel system [12–15]. Harmonic components of circulating current can influence the inverter life cycle, limiting the power rating of the total parallel-connected inverter [16, 17].
The common mode voltage of each inverter is distributed more equally in a carrier cycle, and thus the circulating currents of paralleled modules are mitigated . Furthermore, the reduction methods for low-frequency circulating current can be divided into two categories based on control and modulation [40–67].
Circulating current suppression can effectively improve the reliability and redundancy of parallel inverter systems. The mechanism and influencing factors of the low- and high-frequency zero-sequence circulating current (ZSCC) are analyzed in this study.
